We propose a study of the magnetic structure of isotopically enriched Gd2Ti2O7. We have successfully grown and characterised large single crystals using low-absorption 160Gd. In...

Mixtures of methanol with water and ammonia dominate the chemistry of cometary bodies, leftovers of the building blocks of the outer planets. We have previously determined the...

The mineral mirabilite (di-sodium sulfate decahydrate) has been extensively studied by X-ray and neutron powder and single-crystal diffraction methods. The structure contains an...

In this proposal we request 3 days of beam time on HRPD to study the structure and phase transitions of XNbOP2O7 (X = Rb and ND4). These materials have been shown to undergo...

NaAlH4 has been a model system for metal hydride hydrogen storage materials since the reaction was identified to be reversible. The decomposition pathway has been described by a...

For a decade field-tuned quantum criticality in the spin-dimer system BaCuSi2O6 has been of great interest due to an unconventional dimensional crossover at its quantum critical...

Water molecules can form different hydrogen-bonded networks, a property known as ice polymorphism. So far 18 different networks have been characterized using neutron diffraction...

The combination of the transport properties of liquids with the high thermal conductivity of metals is a promising way of improving heat transfer efficiency and thus reduce...

We request 3 days on GEM to perform in-situ neutron diffraction and electrical conductivity studies of LiBD4 (crystalline and after quenching from 500K) and 0.33LiI.LiBD4 as a...

Orientationally-disordered water molecules in ice adopt a degree of partial order upon cooling, a process that is halted by kinetics at ~100 K in pure ice and ~60 K in KOH-doped...

Nitrides of alkali and alkaline earth metals are an interesting set of materials specifically for their potential in reversible hydrogen storage. However, many fundamental...

Among light metal amide-imide catalysts for ammonia decomposition, lithium-calcium imide is the most promising candidate for practical application. Ex situ diffraction data...

The oxygen transport membrane is a system being developed by St Andrews in conjunction with industry, which at high temperatures will allow the selective migration of oxygen...

This experiment will determine how the structure and porosity of Amorphous Solid Water (ASW) changes when the “ice” is “contaminated” by adsorbate molecules. ASW is a porous...

This proposal aims to study the interactions within a prototypical ionic liquid / co-solvent system. Such systems are currently under investigation as potential solvating media...

SrCuTe2O6 consists of a 3-dimensional arrangement of spin-1/2 Cu ions that are coupled into network of isolated triangles,a highly frustrated hyperkagome lattice consisting of...

We have found that the 134-perovskite, HgMn7O12 (HgAMnA’3MnB4O12) exhibits improper ferroelectric coupling due to an unusual orbital ordering of the manganese cations on both...

The ammonium anion is comparatively soluble in ice and may also increase the solubility of associated cations that would otherwise not be easily accommodated in the crystal...

Many novel electronic ground states form in close proximity to quantum critical points (QCPs), that is, the point where a continuous phase transition occurs at zero temperature....

We propose the investigation of four slag samples coming from an Iron Age furnace in Hüttenberg (Hesse Region, Austria). The materials we intend to measure were recovered from...
